摘要： A sheet member supply device (40) of an image forming apparatus (1) includes a sheet member stacking plate (43) in which sheet members (S) are stacked on the upper surface, a pickup roller (51) which makes contact with, from above, the uppermost layer of the sheet members (S) stacked on the sheet member stacking plate (43), a stacking plate displacement mechanism (44) which displaces the sheet member stacking plate (43) upward, a motive power transmission mechanism (60) which transmits motive power obtained from a drive source (45) to the stacking plate displacement mechanism (44) and a paradox planetary gear mechanism (65) which is provided in the motive power transmission mechanism (60). In this way, with a simple configuration, it is possible to reduce the unintentional downward displacement of the stacking plate.

摘要： A fuser includes a pressure pad forming a nip with a fuser belt between the pad and a fuser rotator. A pressure face in contact with the belt has profiles in planes normal to the axis of the rotator. The profiles each include a reference section, the first to come into contact with the rotator with the belt in between when the pad forms the nip, and a boundary section at a threshold distance from the reference section in the width direction of the nip. When the pad is apart from the nip due to removal of a force applied by a pusher unit, the boundary section is, relative to the reference section, more largely displaced in the opposite direction to that of the rotator in one of the profiles located at a larger distance from a center portion of the pad in the axial direction of the rotator.

摘要： A tension roller which is brought into contact with an inner circumferential surface of an endless belt and is rotated and which can be moved to a first position where the belt is in a relaxed state and a second position where the belt is in a tensioned state, a butting member which butts against the belt, a force application unit which applies, to the butting member, a force acting in a direction opposite to a rotation direction of the belt and a movement mechanism which moves the tension roller to the first position and the second position are provided. When the belt is rotated, the butting member is moved in the rotation direction of the belt by a friction force with the belt, and the movement mechanism moves the tension roller from the first position to the second position by the movement of the butting member in the rotation direction of the belt. When the rotation of the belt is stopped, the butting member is moved in the direction opposite to the rotation direction of the belt by the force applied by the force application unit, and the movement mechanism moves the tension roller from the second position to the first position by the movement of the butting member in the direction opposite to the rotation direction of the belt.
